Steps to Reproduce the Bug

See FTBTeam/FTB-Modpack-Issues#6520 (comment).

Expected Behavior

Able to switch pages to view any bookmarked item.

Actual Behavior

Unable to switch pages (or odd behavior when doing so) when on page two of bookmarks, then open a gui that allows the bookmarks to expand such that all entries fit on one page.

Mod Pack URL (Optional)

https://www.curseforge.com/minecraft/modpacks/ftb-evolution/files/6042342

Mod Pack Version (Optional)

Verified on 1.6.0

Extra Notes (Optional)

The linked ticket is somewhat exhaustive. The bug is actually more easily triggered when using an AE2 terminal, as the GUI for that is larger.

Current workaround is to relocate and resize the bookmarks page (using the initialization file) so there's no overlap with other GUIs.
